There's a comet beginning to make an appearance for northern hemisphere observers--it might become a bright one. I made this sketch and observation early this AM and posted it in the Solar System and Planetary Observing forum.

I worked with HB and 2B pencils and a stump on white Artagain sketch paper and inverted things digitally (also applied 5% blur).

It was cold and I can't sketch with gloves usually, so I kept a HotHands chemical warmer in the muff I wear around my midsection and was able to keep my fingers functioning.

Very nice sketch of this early morning comet. Your techniques always impress me and work so very well. I know what you mean about sketching in the cold, below 25 degrees F I start having trouble with numb fingers. This comet will be fun to follow.

Very nice sketch! I just posted to another link with your sketch where Rev Aaron had started the post to alert observers. It looks as if from projected charts that the comet could reach peak brighteness in February as it moves from Virgo toward Leo and close to Saturn.

If you go to this Ephemeris sitehttp://www.cfa.harva...ets/2007N3.html you will find below the orbital elements a good Ephemeris which includes RA and Dec for selected dates throughout the year. Using a transparent film you can plot these on your favorite star chart for locating on any date by extrapolation. The Heavens above site you copied above gives the coordinates for the date and time you are looking. Look at the data under the first image. I hope this helps.

Thanks, Mark. The charts posted on Heavens Above are for the current day you view the chart. I posted a link on the Planetary and Solar System Observing forum to another chart that will take you through January 31st. Good luck!

Frank, thanks for the encouragement. I hope you get the weather and opportunity to see Comet Lulin soon. The Moon will shortly become a limiting factor, but after that, Lulin will be higher in the sky and hopefully brighter.
